LTC3256 Step-Down Charge Pump DC/DC Converters

Analog Devices Inc. LTC3256 Step-Down Charge Pump Converters are switched capacitor step-down DC/DC converters that generate two regulated outputs over a wide input range. The first regulated output is a 5V output with a direct connection to the charge pump output. The second regulated output is a 3.3V output via low dropout (LDO) linear post-regulator. The converters provide a total output current up to 350mA. Power dissipation is reduced by over 2W at 12V VIN and maximum load on the two outputs.
